5 Formation

5.1 Formation

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

All about Evaporite and Dolomite Properties

Know all about Evaporite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Dolomite belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Dolomite is Earthy. Evaporite appears Glassy, Vesicular and Foilated and Dolomite appears Glassy or Pearly. The luster of Evaporite is subvitreous to dull while that of Dolomite is vitreous and pearly. Evaporite is available in colourless, green, grey, silver, white colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite and that of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
